Benzo[c]phenanthridine skeleton was synthesized from easily available starting N-methyl-o-toluamide 2 and o-methylbenzonitrile 5 in 7 steps. Radical cyclization of styrene 10 afforded 6,11-dimethyl-6,11-dihydro-5H-indeno[1,2-c]isoquinolin-5-one 13. Most 3-arylisoquinolines have displayed strong activities against human tumor cell lines. Especially, indenoisoquinolinone 13 exhibited excellent cy...

The research comprised of studying the effect composting sewage sludge with sawdust and vermicomposting with earthworm Eisenia fetida has on the degradation of 16 polycyclic aromatic hydrocarbons (PAHs). Raw rural sewage sludge prior composting was more contaminated with PAHs than urban sewage sludge, in both cases exceeding EU cutoff limits of 6 mg/kg established for land application. Dibenzo[...

The advent of increasingly stringent and wider ranging European Union legislation relating to water and the environment has required regulators to assess compliance risk and to respond by formulating appropriate pollution control measures. To support this process the UK Water Industry has completed a national Chemicals Investigation Programme (CIP), to monitor over 160 wastewater treatment work...

polynuclear Aromatic Bydromrbons As criteria for the presence of polynuclear aromatic hydrocarbons in tobacco smoke, the list of J. W. Cook (m) has been widely accepted by tobacco chemists. The Surgeon General’s 1964 Report and Cook’s paper are in agreement with respect to the presence of benzo(a)pyrene (3 : 4benzopyrene) , dibenz (a,h) -anthracene (12 : 5,6-dibenzanthrac) : benzo(c) phenanthre...

concentration levels of 16 polycyclic aromatic hydrocarbons (pahs) consisting of naphthalene, acenaphthylene, acenaphthene, fluorine, phenantherene, anthracene, fluor?anthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)p?yrene, dibenzo(a,h)ant?hracene, indeno(1,2,3-cd) pyrene and benzo(g,h,i)perylene were measured in water and sediment samples coll...

The objective of the study was to determine the concentration of total PAHs and to identify the potential sources of contamination in sediments from the Romanian Black Sea sector. Sixteen priority polycyclic hydrocarbons were identified and determined quantitatively in samples of sediment collected from marine areas (depths over 20 m) from the 12 stations located between Sulina and Mangalia, du...

Concentration levels of 16 polycyclic aromatic hydrocarbons (PAHs) consisting of naphthalene, acenaphthylene, acenaphthene, fluorine, phenantherene, anthracene, fluor?anthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)p?yrene, dibenzo(a,h)ant?hracene, indeno(1,2,3-cd) pyrene and benzo(g,h,i)perylene were measured in water and sediment samples col...

Pollution of the environment by polycyclic aromatic hydrocarbons (PAHs) is great concern because their persistence, toxicity, mutagenic and carcinogenic nature. The distribution 8 PAHs in water surface sediment from M’Badon Bay (Ebrie Lagoon, Côte d’Ivoire) was investigated using high performance liquid chromatography (HPLC). results showed that mean PAH concentrations ranged 0.08 to 2.70 µg/L ...

Present study was undertaken to examine the extent of Polycyclic Aromatic Hydrocarbons (PAHs) contamination in neighbourhood lithospheric environment of landfill site situated in eastern outer edge of Kolkata metropolitan city in West Bengal, India, along with its sources identification, spatial distribution and probabilistic cancer risks to residents. The collection and analytical tests were p...

The mass, chemical composition and toxicological properties of fine particulates (PM2.5) emitted from cooking activities in three Hong Kong based restaurants two simulated experiments were characterized. Extracts the PM2.5 samples elicited significant biological [cell viability, generation reactive oxygen species (ROS), DNA damage inflammation effect (TNF-α)] a dose-dependent manner. PAHs, oxyg...
